1495 6742 d 4 h jermar /kernel/trunk/ Remove three infinite loops introduced yesterday :-)

Make ia64 ready to load 5 ELF images.		  
1210 6783 d 16 h vana /kernel/trunk/ Incomplete VHPT walker support for Itanium  
1191 6790 d 20 h jermar /kernel/trunk/ Kernel support for SYS_ENABLE_IOSPACE.
amd64 and ia32 provide dummy implementation thereof.		  
1106 6813 d 7 h jermar /kernel/trunk/arch/ Pass either -DCONFIG_PAGE_PT or -DCONFIG_PAGE_HT to the compiler.  
1059 6819 d 9 h jermar /kernel/trunk/ Clear user address space when creating new page tables.
Fix mapping of l_apic and io_apic on amd64.		  
1053 6819 d 12 h vana /kernel/trunk/ Itanium FPU Lazy context switching... but not so much tested  
938 6823 d 11 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
919 6826 d 16 h jermar /kernel/trunk/ ia64 work.
Changes to make userspace work (kernel part).
Use ski.conf from contrib directory to run Ski.

There is actually no appropriate syscall handler yet.		  
901 6834 d 18 h jermar /kernel/trunk/arch/ ia64 work.
Provide PA2KA(identity) mapping for kernel data references via Alternate Data TLB Fault handler.
Add before_thread_runs_arch() that maps kstack, if necessary.
Add easy to use dtlb_mapping_insert() for comfortable insertion of kernel data mappings.		  
811 6856 d 9 h jermar /kernel/trunk/ Fix number of steps in softint division.
Make ia64 port compile with softint.		  
756 6863 d 5 h jermar /kernel/trunk/ Memory management work.
Remove the last (i.e. 'root') argument from page_mapping_insert() and page_mapping_find().
Page table address is now extracted from the first (i.e. 'as') argument.
Add a lot of infrastructure to make the above possible.
sparc64 is now broken, most likely because of insufficient identity mapping of physical memory.		  
753 6864 d 12 h jermar /kernel/trunk/ Convert ASID management of ia64 to ASID FIFO mechanism.
18-bit RIDs are supported.		  
740 6870 d 14 h jermar /kernel/trunk/ ia64 ASID management code (not tested).  
727 6875 d 7 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
684 6886 d 14 h jermar /kernel/trunk/ Memory management work.
Move generic 4-level page table interface to genarch
and enable architectures to use different virtual memory
mechanisms (e.g. page hash tables).
Start page hash table support.
Switch ia64 and sparc64 to page hash tables.
Other architectures keep on using 4-level page table interface.		  
674 6890 d 17 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
583 6915 d 14 h jermar /kernel/trunk/arch/ia64/ Fix IA-64 so that it compiles again.
Characters are not recognised correctly.		  
539 6920 d 10 h jermar /kernel/trunk/ Buddy allocator cleanup and fixes.
- Add some comments.
- Update zone information on frames allocation/deallocation.		  
534 6921 d 9 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6921 d 9 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.
